Algoriddim's djay 2.5 for iOS drops today with a significant addition that belies its modest ".5" version number – Spotify support. This is a huge deal because it's like having a pair of turntables on your iPad and 20 million tracks to spin on them. Now you can scratch, remix, and mash up music from Spotify's massive catalog without having to build, curate, or manage playlists – and without having to pony up the cash for a 128GB iPad.

Another huge feature in djay 2.5 is Match, a track recommendation tool powered by The Echo Nest, the leading music intelligence software company that Spotify acquired in March. The Echo Nest does its magic with a combination of human data, machine learning, and algorithms. Its customers include Rdio, MOG, iHeartRadio, and Spotify.

Match allows you to play one track and have djay recommend (and queue) similar songs – think iTunes Radio or Pandora on a set of turntables. Match takes your mix to the next level by recommending tracks based on danceability, BPM, key, music style, and how well the song mixes with the currently playing track. If you're hosting a party or event its easy to start one song and have djay spin the rest of the night via the enhanced Automix Radio feature.

Most impressive is djay's ability to stream tracks from the cloud without missing a beat. The Spotify tracks play just like local tracks and it's impossible to tell them apart. It's a credit to the Algoriddim engineers that the Spotify streaming is so smooth. Tracks download extremely fast (four to 10 seconds in my testing) and are instantly able to be scratched, scrubbed, and even played backwards.

The Spotify integration requires a $10 per month Premium account ($5/month for students) and is available in all markets with all tracks. If you're not a Spotify subscriber, Algoriddim is offering new djay customers a free seven-day trial of Premium. As a longtime djay user I can confidently say that 2.5 is the best reason to subscribe to Spotify yet. Having 20 million tracks at your fingertips gives DJs a new level of convenience never before available and the Match feature is the icing on the cake.
